    I know you don't wrench on the threads.

      Oh, then why this advice:
      There's no spot for your wrench, meaning your wrench will tear up the threads, and probably leak.

          Anyway, this makes sense. However I have never had a close nipple bottom out before that I recall. They always reached proper torque before the fittings touched. Of course I rarely have used them, usually I use 2" nipples at the shortest.

            I forgot bushings. The standard is in the National fuel gas code. I'm not sure if it's in the upc or not.

            What I heard years ago on close nipples was that because the entire nipple is threaded there is an insufficient amount of steel and they can rust through.

              Agreed. For the same reason, its states in our code that if using a bushing, you MUST reduce more than one pipe size.
